Hi there, first we find the multiples of 7, 7*1=7, 7*2=14, 7*3=21, 7*4=28, 7*5=35, 7*6=42, 7*7=49, 7*8=56, and 7*9=63. Therefore, the answer would be 56.
Answer:
The answer is 2/7
Step-by-step explanation:
when you divide 1/3 you get .3333 and when you divide 2/7 you get .287. This means that when you move the decimal and convert to a percentage, 33.3% and 28.7%, 2/7 is closer to 30% because it is only 1.3% away versus 3% away from 30%

Answer:
0.23
Step-by-step explanation:
X^2 - 18x - 144 = 0
Factorise:
We choose 2 numbers that add to -18, and multiply to 144, these numbers are +6 and -24, we put it into the brackets:
<span>(x + 6)(x - 24) <- x = the interted sign of the numbers inside the brackets
E.g. +6 turns into -6 and -24 turns into +24
x must = -6 or = +24
</span>
Answer:
(20, -2)
Step-by-step explanation:
Given the coordinate vectors p=(4,3) and q=(-2,7),
4p - 2q = 4(4, 3)- 2(-2, 7)
4p - 2q = (16, 12) - (-4, 14)
4p - 2q = (16+4, 12-14)
4p - 2q =(20, -2)
hence the required vector is (20, -2)
